Ernest Hemingway's first, and arguably most important, novel, about the post-WWI "Lost Generation," wasn't made into a movie until 1957. By then, producer Darryl F. Zanuck pulled out all the stops, casting top leading man Tyrone Power as Hemingway's alter ego, the impotent Jake Barnes, and former leading man Errol Flynn as the alcoholic Mike Campbell. Both Power and Flynn would be dead in two years. Ava Gardner plays Lady Brett Ashley, who substitutes a life of promiscuity for the love she cannot share with Jake, and Mel Ferrer is Robert Cohn, who is helplessly obsessed with Brett.
